Another mild color scheme for the KDE desktop, this time mainly based on violet (see screenshots)
Please complete this color scheme with the related Plasma 5 theme and the related QtCurve presets downloadable on this website at my page.

You can also use the Breeze widgets with this theme but I find the QtCurve widgets to be better suited.
GTK2 applications are also rendered correctly using QtCurve! See screenshot (GIMP). For those using Audacity, this theme is OK too.
